What factors are associated with a better restoration of pelvic version after adult spinal deformity surgery?

Introduction: Poor restoration of pelvic version after adult spinal deformity (ASD) surgery is associated with an increased risk of mechanical complications and worse quality of life. We studied the factors linked to the improvement of postoperative pelvic version.

Materials And Methods: This is a retrospective analysis of a prospective multicenter ASD database.

Compensatory mechanisms recruited against proximal junctional kyphosis by patients instrumented from the thoracolumbar junction to the iliac.

Purpose: The compensatory mechanisms recruited by un-instrumented patients against sagittal imbalance are well documented. However, there is a lack of information regarding instrumented patients.

Material And Methods: We performed a retrospective analysis of data collected prospectively in a multicenter adult spinal deformity database.
